Unable to active Windows Server 1909

[MikeRM2]

Good evening everyone,  I am having a problem activating Windows Server 1909.  When I installed it, I did not have a box pop up to enter the key.  When it finished installing, I entered sconfig then selected Windows Activation.  From there I selected Install Product Key.  I entered in the product key and was met with an error in the script.  0x0C004F069 On a computer running Microsoft Windows non-core edition, run 'sliu.exe 0x2a 0x0C004F069' to display the error text which basically tells me the SKU is not found.  But if I got the key from Microsoft for Windows Server 1909 how could the SKU not be found?  Anyone have thoughts on how to activate the server?

Only microsoft can help you with this one.

@Dave PatrickWell I gave Microsoft a call, and after an hour on the phone, two people talked to, and multiple steps taken.  I am no further along in getting it activated.  The unfortunate thing, is they kept asking me to go to settings, and hit the Windows+R keys (Had to tell them the keyboard didn't have windows key, there was absolute silence for about a minute after I said that), and trying to hit the windows icon with the mouse; I kept telling them I only have a command prompt since it is Windows Server Core, not a GUI system.  I was even told there is no such thing as Windows Server Core.  So my confidence level in getting this activated with their help is not a high level.

If I was to install Windows Server 1803, activate it, then upgrade to Windows Server 1909 should the activation retain?

Are you using KMS to activate?

@Dave PatrickNo I am not using KMS to activate.  I did try and set up a KMS host earlier today, but that failed for the key that was used as I do not have any KMS keys.

You'll have to work with Microsoft to resolve these activation issues.
